Use the structure of an expression to identify ways to rewrite it. For example, see x<sup>4</sup> â y<sup>4</sup> as (x<sup>2</sup>)<sup>2</sup> â (y<sup>2</sup>)<sup>2</sup>, thus recognizing it as a difference of squares that can be factored as (x<sup>2</sup> â y<sup>2</sup>)(x<sup>2</sup> + y<sup>2</sup>).

Warm-up

10 minutes

Each day, students complete a Warmup that usually consists of spiraling the previous day's material, in addition to older material. Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.

Today's warm-up provide a "mixtape" of sorts to give kids a small amount of review daily that goes a LONG way toward retention of concepts.

Task #2 is a good one to spend time looking at student work - often, students forget to apply the exponent to everything inside the parentheses, and this question is designed to catch and remediate that.
